GUN-SIGHT.

Specification of Letters Patent.

Patented Julie 4, 1912.

Application led October 27, 1910. Serial No. 589,488.

To all whom t may concern Be it known that I, JOHN R. JONES, a citizen of the United States, and a resident of lVesternville, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Grun- Sights, of which the following is a specification, reference being had to the accompanying drawings.

The object of the present invention is to provide an improved peep sight which embodies novel features of construction whereby a fire arm to which the sight is attached can be accurately and quickly aimed, the said sight being adjustable toward or away from the eye of the marksman and being adapted to be raised and lowered to regulate the elevation.

A further object of the invention is to provide a peep sight of this character which is comparatively simple and inexpensive in its construction, which can be readily placed upon the general run of lire arms as they are now manufactured Without necessitating any changes therein, and which enables each individual marksman to adjust the peep member according to the requirements of his eye sight so as to obtain the best results.

With these and other objects in view, the present invention consists in the combination and arrangement of parts as will be hereinafter more fully explained and particularly pointed out in the appended claims, it being understood that changes within the specific structure shown and described may be made within the scope of the claims, without departing from the spirit of the invention.

In the accompanying drawings, forming a part of this specification, and in which like numerals of reference indicate similar parts in the several views z-Figure 1, shows a fragmentary view of a gun barrel provided with my improved sight. Fig. 2, shows a detached detail in section of the breechsight. Fig. 3, shows a detail of a flanged spring plate as used in my invention. Fig. 4, shows a rear end View of the breech-sight. Fig. l5, shows a detail of the cross plate. Fig. 6, shows a detached detail of the ratchet plate. Fig. 7 is a central sectional view through the breech sight, disclosing a telescope as attached thereto.

In connection with lire-arms intended for long ranges, it is quite necessary to have a sight which is marked for different distances, which distances are determined by certain elevations imparted to the breechsight. It is further quite essential that the sighting mechanism be so constructed that the fore-sight and the breech-sight can be brought into positive alinement, in order to eliminate as much as possible the personal error of each marksman.

In the accompanying drawings the numeral, 1, designates a gun barrel, which, at its forward end is provided with a transverse key slot, 2, arranged to receive the chamfered edge base, 3, of the fore-sight, 5, which has the curved sight-ing edge, 6, ending in the upstanding sight edge, 5. This fore-sight is securely fixed on the gun barrel. Near the breech end the barrel, 1, is provided with a second key slot, 7, within which is securely held the key block, 8. rl"his key block, 8, is provided with the pin, 10, by means of which the spring plate, 12, is securely fixed to the key block, 8. This spring plate, 12, is attenuated near its forward edge, as shown at 11, while the rear edge has the lower lengthwise running slot, 13, and the oppositely positioned edge flanges, 17. Below, the under surface of the spring plate, adjacent to the slot, 13, is provided with a seat, 15, running the full width of the plate, as shown in Figs. 1 and 2. The rear end, 16, of the spring plate, 12, is in frictional contact with the gun barrel, 1. Slidably held to the spring plate, 12, is a peep-sight in the form of two cones, 18, 18, the smaller ends of which are connected to provide a centrally positioned sight aperture, 19, shown in Fig. 4, and indicated by dotted lines in Fig. 1. This peep-sight has four outstanding ears, 20, slidably held below the edge flanges, 17, so that this peepsight may be shoved backward and forward upon the carrying spring plate, l2. Spanning from one flange, 17, to the other is the cross plate, 16', which is secured to the flanges by means of the screw, 17. This cross plate, 16', is centrally located below the duplex peep-sight, 18. Slidably held upon the gun barrel, 1, is the curved saddle plate, 22, to which is secured the upstanding ratchet plate, 23, having the notches, 24, of successive higher elevations. The notches, 24, are arranged for co-action with the cross plate, 16', and it is by means of this ratchet plate that the peep-sight can be elevated or depressed.

As shown in Fig. 2, the ratchet plate, 23, is of a length considerably less than the slot, 13, so that the ratchet plate can be carried backward and forward within the middle lengthwise running slot, 13. At the same time the duplex peep-sight is slidably connected to its carrying plate, 12, so that the peep-sight can also be carried backward and forward.

In Fig. 1, the broken line, a', represents the line of sight, and, a, the eye of the marksman. As shown, the peep-sight, 18, can be carried away from or toward the eye of the marksman, without elevating or depressing the sight in simply shifting the saddle plate with the peep-sight when it is desired to change the position of the peepsight, without changing the elevation. It is, of course, understood that the slot, 13, is of any required length. In making the peep-sight, 18, slidable, independent of the ratchet plate, 23, a very important advantage is gained, in that the sight aperture, 19, can be accurately adjusted to meet the personal requirements of the marksman using the peeps. This is extremely important in that some marksmen are nea'rsighted and some farsighted, and the aperture, 19, must be consequently adjusted to meet the personal requirements of the marksman. In turning the gun, the sight edge, 5, is to be brought into accurate alinement with the sight aperture, 19. As both of the members, 18, are funnel shape, the breech-sight can be raised and lowered in a manner insuring the aperture, 19, being held centrally and in unobstructed range at all times.

In F ig. 7 I show a modification where I provide the breech sight with a telescopic attachment. To one end of the member 18 is secured the lens 28, by means of the ring 27 screwed to the member 18, while upon the opposite end I screw a cap 25 having the sleeve 26 slidably holding the telescope 29 having the forward lens 80. By means of this telescopic attachment, the efficiency of the sight is increased.

It is, of course, understood that these gun sights are made of various sizes, and of any suitable material. A gun sight constructed according to my invention is further extremely simple and inexpensive in construction and both durable and efficient in operation, and the sight adjustments can be made with ease, accuracy and despatch.

Having thus described my said invention what I claim as new and desire to secure by United States Letters Patent, is:-
